00 GS400 w/130k miles, stock.

For the last few days my cars radiator fan turns on immediately everytime I turn on the engine. Doest matter what the temperature is outside. Even on cold start up, the fan still kicks in. it does however shuts off after a while or so, I think - dont pay 100% attention but FORSURE it kicks in every start up now regardless if the enegine has been running or not and temperature.

Is there a bad sensor causing the radiator fans to kick in everytime I turn the key or whats going on?

Thanks in advance.

 

?????????????????

 

do you have the A/C on ? because it will turn on if you have it on... just to be safe check your coolant level

 

Mine does the same thing too when the weather is at 30deg then it will shut off automatically. I think its normal.
